My invention relates to a refrigerator construction.

lt is an object of my invention to provideV a refrigerator cabinet which can be made in knock-down parts which may be eas-ily assembled in cabinet formation. Y

It is a further object to provide a construction in which the four sides andthe top and bottom may each be made andassembled in the shop as units and the units afterward secured together in cabinet formation by securing opposite sidesrto each oth-er.V

And in general, the object is to provide a very strong7 durable and efficient refrigerator which may be cheaply manufactured.

My invention in its preferred form comprisesfour side units, a top and kbottom unit, all' of which parts after assembly are secured and held together in cabinet formation by simple means passing between opposite side units.

Fig. 11 is a fragmentary inside elevation of the front unit shown in Fig. 9.

Fig. 12 is a fragmentary view of the form of cabinet shown in Fig. 9havingfront removed. f V l Fig. 13 is a detail perspective of a front corner post showinga fillet member abutment for a door.V

Referring now particularly to Figs, 1 to 8, 5 5 designate the two end units as a whole.

Each of the ends preferably comprises corner posts 6 7 and upper and lower framing pieces 8 9. These posts and framing pieces maybe mitered and secured together in any suitable manner as by means of the corner fastenings 10-10. The posts and framing members,fconstituting the end frame. are of substantially the same cross section and in the preferred form are substantially of the section shown in Fig. 8. As shown in said figure there is provided in one side ofthe post a relatively wide groove 11. Extending within the member, preferably from the same side7 is an aperture or relatively deeper groove 12. Upon another side may be provided spaced grooves 13 14, and the inner corner may be rabbeted or cut away as at 15. The two end units are preferably duplicates of each other.

The front unit comprises a frame made up of frame members such as 16-17. Secured between'twof'of the frame members of the front unit there may be a horizontal cross beam`18 and a vertical beam' 19 may be secured between another frame member and the cross beam 18. The frame members,

be correspondingly beveled for the purpose of more securely clamping or holding the parts together.

The front panel unit frame in the form shown is arranged to be substantially Iilled by doors and the inner part of the frame and beams are provided with ledges such as 22, which act as abutments or jambs for the doors. Y j j The top unit preferably 'comprises two framing4 pieces 242-25, and two tie beamsy or end members 26e-27. The framing pieces 24e-25 are preferably of the same cross section as the members constituting the frame of the end units and the description thereof given will suffice foryadescription of them. The framing pieces .Q4-25 are preferably provided with projections 28, and the tief beams 426--27 may have projecting tongues i or projections 29 flush with the projectlODS The bottom unit is preferably made as a duplicate of the top and no separate descrip' `tion thereof is necessary.

The back unit may comprise a frame substantially similar to the frame constituting the front unit hereinbefore descrilired. back unit will also be provided with tongues or` projections 30-30 for` interengagement j with the g and bottom units. i Suitable insulating panels may be secured in the grooves provided for them in the ends, top, bottom and back units. course, obvious that if thel front unit be not substantially filled by doors, thensuitable insulating' panels would likewise be progroves in the end units and the top vided in the frontun'it. j j, The parts are secured together in cabinet formation in the preferred form by means of bars or rods 3l-31.

TheV parts may be assembled irL cabinet formation in the following' manner r One end unit is first positioned.A "The front unit may next be engaged with the end and the projection 2O placed' in the groove 12. The back unit may next be engaged with the end unit and the projection 30 in a similar man ner placed in the proper groovein the back corner post. The top and bottom members may next be engaged with the end and the projections or tongues 28 `and 29` fitted into the grooves in the framing members 8 `9. `When the parts are thus farassembled the last end unit is putin place with the respective tongues or projections of the afore` mentioned parts nterlitted with the grooves in the last end in a manner similar to that just described for the first end unitl The parts'are now ready to be secured together.

The preferred means forv securing the parts in cabinet formation are rods or bars passing transversely through oneend unit,.:

longitudinally through the grooves l2 in the 'first form of my invention.

of the post is a relatively wide groove 38v The y 1t is, ofv

. doors. I Y

The back panel unit comprises corner` framing pieces'of the top and bottom units,

and then through the opposite end unit.`

Suitable nuts and heads may be provided on the rods for drawing the end units together and securing all of theparts rigidly andv securely together in cabinet formation. v 1n Figs. 9 to l2 l have shown a slightly 'modified form of my invention in which the partsare held together by means ,passing v,through,and securing thefront and back able or desired mea-ns, such as the corner fastenings Bil-37. y v

The-'corner postsand framing 4pieces are preferably of the same cross section andin Fig. 13 I have shown a preferred form of sectionl` .This section isA substantially the same as that described in connection with the At one side and there is providedan aperture 39 through4 the .post which in the preferred form is in the form `of a deep groove extending below the groove 38.' 1n another side of the post spaced apartV grooves It() are provided and the inside corner may be rabbeted or cut away as at 41'.. f i

In order to provide proper jambs or abutments for doors, suitable beams such as il-442 may be provided between the posts and framingemembers.. The front unitis provided with fillet membersad fittingfin the grooves Ll0 ofthe posts, framing jmembersj `and-beams. rlhe fillets constitute in conjunction with the posts 45p-4:6 `and framing pieces secured thereto in a manner similar to that described for the front unit. VThe baclrcorner posts are preferably of' the same'cross section as the front corner posts.

posts, jambs for the i T he side panel units each comprise 'frames` Y 47148. Projections, such as 49, are provided about the outside Vof the side frames for interiitting with grooves in front, backy insulating `panels to closeY `the space not l closed by doors. v The top and b ticularly in Fig. 12, preferably comprise framing 'pieces' 55s-.5o` which are of sub,v

stantially. the same *cross section as the posts and framing pieces hereinbeforede-1 ottoni unitsl as shoivnparscribed. Suitable tie beams 57-58 secure the top and bottom framing pieces together and maire up top and bottom frames. The members 55-56 may be provided with projections 59-60 and the tie members 57-58 may have longitudinal tongues or projec- 1. tions til-62 abutting the projections S9-60,

shown in Figs. 6 and 7.

and substantially flush therewith.

It is of course understood that insulating panels may be provided in the top and bottom frames in a manner similar to that Securing means shown in the form lof rods 63, may `be used to hold the parts together in cabinet formation.

To assemble the parts in cabinet forma` tion, one of the sides, preferably the front, is first positioned. The end units are next put in place with the projections 49 on the frames fitting in the grooves 38 in the front unit. rlhe top and bottom units may next be put in place with the projections 59-60 and the tongues 6l-62 fitted in the grooves 38-38 in the top and bottom framing pieces. The back unit is next put in place with the projections and tongues on the sides, top and bottom units fitting in the grooves in the back unit in a manner similar to that described for the front unit.

In order to secure the parts together in cabinet formation, the rods 63 are passed transversely through apertures in the corners of the front unit, longitudinally through the apertures or grooves 39 in the top and bottom units and then transversely through apertures in the back unit. Heads and nuts maybe provided on the rods for drawing the front and back units together and rigidly and securely holding all of the parts together in cabinet formation.

It will thus be seen that I have provided a knock-down refrigerator consisting of but few separate parts which may be very compactly stored for shipment and which may be quickly and easily put together in a very simple manner.

In the specification and Claims I employ the term sides to designate broadly the front and back units as well as the sides or ends proper.
